Description

The scaffold for construction work equipped with fall prevention means}

The present invention relates to a scaffold for construction construction equipped with fall prevention means. To be described in more detail, a worker falls or a falling object occurs on the outside of the scaffold from the pipes and scaffolding that constitute the scaffolding installed during the construction, demolition, and repair process of the building. This relates to scaffolding for construction work equipped with fall prevention measures developed to prevent people from falling and to be aware of dangerous situations.

Scaffolding is being installed at various construction sites to secure space for work while allowing workers and construction materials to move, and such scaffolding is constructed by connecting scaffolding to a structure made of a plurality of pipes.

Injuries caused by workers' falls or falling objects are a constant occurrence at these sites, and although it is mandatory for workers to have helmets and safety ropes to prevent falls at sites, accidents still occur because these are not followed in actual sites.

Accordingly, in various prior arts, various types of safety devices have been developed and applied as a way to prevent accidents. However, when a sound alarm is applied when the worker's position moves to the outside of the scaffold, the worker must be fully aware and pay attention to the work. If you are forced to move for the sake of it, there is a risk of becoming annoyed or startled by an alarm.

Moreover, it is natural that various sensors and means for alarms are highly effective, but they require power, so considering the connection to an external power source and the installation of various devices including sensors, it is difficult to actually apply them at construction sites in harsh conditions. .

In addition, when safety measures, such as handrails, are provided, the construction of the scaffold becomes more complicated, which increases the construction cost and period, and the movement of various items for work, that is, in situations where some cannot be directed to the outside of the scaffold, causes the scaffold to be attached to the railing. This causes inconvenience when items get caught.

Therefore, there is a need for research into more diverse means that are easy to construct, allow workers to recognize and hear alarm sounds, and provide maximum protection to workers in the worst-case scenario of falling.

The present invention is a means to prevent workers from falling from scaffolding to secure movement passages and work spaces for workers in scaffolds installed outside the building in the expansion or remodeling of buildings, and in the case of an electrical system for fall prevention, connecting the power source. This is to solve the problem that the means for this are complicated and that installing separate railings requires a lot of cost and construction and demolition time.

That is, according to a preferred embodiment of the present invention, the safety belt 123 wound by the winding roll 121 inside the safety belt 123 applied to items such as tape measures or blinds has a structure that is pulled out when pulled. When the upper body (12) is coupled and fixed to the footrest (1) and the lower body (13) is pulled, the safety belt (123) is pulled out and the lower body (13) uses a strong magnet (131) to use the lower footrest (1). ) or attached to the upper body 12 or pipe 2, it becomes a means of primarily preventing workers from falling due to the plurality of safety belts 123.

When the lower body, which is in close contact with the upper body, is pulled and attached to the footrest or pipe consisting of the lower layer using the supporting force of a magnet, the wound safety belt is pulled out and acts as a safety railing, making installation convenient, and the lower body remains intact even when dismantled. When pulled and attached to the upper body, the safety belt is wound inside the upper body for convenient storage and movement.

At this time, it can be said that the most common structure of the winding means 124 is to have an elastic restoring force with respect to the rotation direction by a torsion spring as shown in the drawing.

In addition, in the present invention, the cut portion 122 is in close contact with a seat belt 123 that extends downward from the opposite side of the footrest 1 and extends vertically downward, and when the seat belt 123 is pulled out over a certain length, an alarm sounds. An embodiment is presented wherein an alarm device 125 that sounds is installed.

When the worker contacts the safety belt 123 and is pushed outward during work, the safety belt 123 is further pulled out from the upper body 12, and in a more serious situation, the safety belt (123) is pulled while the worker is completely separated from the footrest 12. When the seat belt 123 is pulled while hanging on the lower body 13 separated by 123) or an external force, an alarm sounds to notify the worker and the surrounding area to prevent an accident or provide rescue.

As shown in Figure 3, in this application, one end of the winding means 124 is fixed to the winding roll 121 and the other end is fixed to the upper body 12, so that the safety belt 123 is released and the winding roll 121 It consists of a torsion spring that, when rotated, expands in diameter and acts as an elastic restoring force;

The alarm device 125 is configured to penetrate the upper body 12 by screwing and its end is in close contact with the torsion spring, so that an alarm sound is sounded by a built-in device when the torsion spring is expanded and pressurized. An example is presented.

At this time, the torsion spring also has various shapes, but in the present application, one end is bent and extended inward and inserted into the winding roll 121 to rotate according to the rotation of the winding roll 121, and the other end is extended in a tangential direction to form the upper body 12. ) is the most common to have a shape that is fixed to.

In addition, the part of the alarm device 125 that is in close contact with the torsion spring is a kind of limit switch, and it is desirable to apply the simplest structure that can emit an alarm sound with a built-in power source. As shown, it is screwed to the upper body 12. It is shown that it is configured so that the distance to the torsion spring can be adjusted by making it penetrate and rotating it from the outside.

In addition, the safety belt can be extended directly to the lower vertical as shown in FIG. 2 or can extend downward after crossing the adjacent horizontal pipe (2) as shown in FIG. 4. After construction, the alarm device 125 is rotated from the outside. An embodiment is shown in which an alarm sound is sounded even when the seat belt 123 is slightly withdrawn by having a structure that can adjust the degree of insertion.

The alarm device adjusts the insertion degree of the operating switch from the outside of the upper body by rotating the screw connection, allowing fine setting of the degree of withdrawal of the safety belt, thereby improving the sensitivity of the alarm sound transmission through easy adjustment, thereby improving the work safety of workers. It can be improved.

Figure 5 is a diagram showing a state of use according to another embodiment of the present invention, wherein the seat belt 123 extends obliquely from the top to the bottom at an angle of 10 to 20 degrees, and extends obliquely in opposite directions to the adjacent seat belt 123, forming a plurality of An embodiment characterized in that it is formed in a V-shape or a W-shape was presented.

In the above embodiment, when the seat belts 12 are formed vertically at regular intervals, the worker can fall while spreading the seat belts 123 on both sides. In this embodiment, the shape opened at the top narrows toward the bottom, so that the body is It is easy for the worker to get caught or hang by holding the safety belt 123, and conversely, the shape that opens at the bottom can be said to be a structure that prevents separation due to the dense upper part.

Figure 6 is a diagram showing a state of use according to another embodiment of the present invention, wherein the safety belt 123 extends horizontally between the upper and lower footboards 1 and does not have a pipe 2 that can serve as a handrail. An embodiment is shown in which one or more horizontal safety belts (126) are additionally provided to sequentially horizontally connect and secure adjacent safety belts (123).

This embodiment is usually constructed with one or two pipes (2) extending horizontally between the upper and lower scaffolds (1) to reduce the worker's fall in the form of a two-stage handrail, but these pipes ( This is an embodiment to prevent the risk of accidents during work from increasing if 2) is not present.

At this time, the horizontal safety belt 126 has the simplest structure and can be connected by forming holes penetrating the safety belt 123 at regular intervals and providing hooks that are caught in these holes. In addition, connection and fixation is possible in various structures.

In addition, as the number of horizontal safety belts 126 increases, a net structure can be created to further ensure safety, and most of the existing various fall prevention measures are not actually applied because they are impossible to construct or require excessive equipment and construction costs. This institute has developed a method to prevent falls that has the cheapest device structure and is the easiest to construct.
